The purpose of this study was to assess the pain-relieving effect of iontophoretically applied prednisolone on the patients with temporomandibular joint (TMJ) pain, 30 TMJ pain patients participated in this study. Inclusion criteria for subject
selection were 1) tenderness of TMJ on palpation and 2) visual analog scales(VAS) of above 20 mm. The patients with polyarthralgia, rheumatic arthralgia, and systemic diseases were excluded for this experiment. The patients were randomly assigned
to one
of three groups; (1) Group 1 for administration of 2% prednisolone, (2) Group 2 for administration of 1% prednisolone, and (3) Group 3 for administration of saline. Phoresor PM600(r) (Motion Control Inc., Utach, U.S.A.) was used for
administration
of
drugs by iontophoresis. Baseline and post-medication pain levels were recorded by VAS, pressure pain threshold (PPT), and palpation index (PT). Post-medication data were compared with baseline data for each group.
@ES The results were as follows :
@EN 1. All the groups showed significant decrease of VAS scores after treament.
2. PPT was significantly increased only in Group 1 and 2 not in Group 3.
3. PI was significantly decreased only in Group 1 and 2 not in Group 3.
